Re: restoring paint
Yep, I can see the difference in the hood and those quarter panels. Unfortunately, red can be bad for having individual panels fading like that. You're probably going to have to invest in a good DA buffer.
First thing to try would be the oxidation remover suggested earlier. Something like Meguiars ColorX might work.
It's likely though that you will need something a little more serious for that. A strong Rubbing Compound used properly and probably more than once should have a strong effect on that fade.
However, it's possible that over a week or two the fading will return. If that happens then that means the surface (hopefully just the surface) of the paint is, in the simplest of explanations, dried out. You could have a professional check it out at this point and tell you what they think about if it's restorable or not. He'll most likely tell you to repaint it. He might have some other advice for you. If he doesn't you only have one other option but it takes serious consideration before deciding on whether to do it or not.
If it's just the surface of the paint, or the clear coat, then you do have the option of wet sanding. This method leaves you with no clear coat when you are finished. Because of this you will need to take the best of care of your paint from this point forward. This means polishing it to restore moisture and waxing it to cover and protect it on a regular basis. The wet sanding process needs to be researched extensively before attempting as well. This is not something take lightly as you are putting an abrasive surface on your paint and if done to much or to intensely you can go right thru your paint to the primer or worse metal. If this happens you WILL have to repaint the panel.
Most places will suggest using 1000 grit wetsanding paper to wet sand your car. I would suggest taking a step further and using 2000 grit so you're removing less paint with each swipe. You'll need a sanding block so that you are applying even pressure across the entire piece of sand paper. Do not try to sand this by hand. You will end up with minute grooves in your paint caused by your fingers. You will need a constant supply of clean water, maybe some detailing spray to use as lubricant. You will also need to watch several videos about doing this process. Watch a few so that you get techniques from multiple people. This explanation does little not provide enough information to go out and do this process. It would take too long to explain every preparation that needs to be done and every step that is taken.
After the wet sanding you will have to buff the panel with rubbing compound again to remove the surface damage caused by the sand paper. It may take a couple of passes on each panel to remove all of the scratches and to make the surface shine. After that you will want to polish the panel and then wax it properly.
After the wet sanding your paint will not have any clear coat paint to protect it from the sun. It will require more than normal vigilance with regards to washing, polishing and waxing.
